ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 6-2: Generic standards – Immunity for industrial environments

1 Scope and object

This part of IEC 61000 for EMC immunity requirements applies to electrical and electronic apparatus intended for use in industrial environments, as described below Immunity requirements in the frequency range 0 Hz to 400 GHz are covered No tests need to be performed at frequencies where no requirements are specified

This generic EMC immunity standard is applicable if no relevant dedicated product or product-family EMC immunity standard exists

This standard applies to apparatus intended to be connected to a power network supplied from a high or medium voltage transformer dedicated to the supply of an installation feeding manufacturing or similar plant, and intended to operate in or in proximity to industrial locations, as described below This standard applies also to apparatus which is battery operated and intended to be used in industrial locations

The environments encompassed by this standard are industrial, both indoor and outdoor Industrial locations are in addition characterised by the existence of one or more of the following:

– industrial, scientific and medical (ISM) apparatus (as defined in CISPR 11);

– heavy inductive or capacitive loads are frequently switched;

– currents and associated magnetic fields are high

The object of this standard is to define immunity test requirements for apparatus defined in the scope in relation to continuous and transient, conducted and radiated disturbances, including electrostatic discharges

The immunity requirements have been selected to ensure an adequate level of immunity for apparatus at industrial locations The levels do not, however, cover extreme cases, which may occur at any location, but with an extremely low probability of occurrence Not all disturbance phenomena have been included for testing purposes in this standard, but only those considered as relevant for the equipment covered by this standard These test requirements represent essential electromagnetic compatibility immunity requirements

NOTE 1 Information on other disturbance phenomena is given in IEC 61000-4-1

Test requirements are specified for each port considered

NOTE 2 Safety considerations are not covered by this standard

NOTE 3 In special cases, situations will arise where the level of disturbances may exceed the levels specified in this standard e.g where an apparatus is installed in proximity to ISM equipment as defined in CISPR 11 or where

a hand-held transmitter is used in close proximity to an apparatus In these instances, special mitigation measures may have to be employed

NOTE 4 The industrial environment may be changed by special mitigation measures Where such measures can

be shown to produce an electromagnetic environment equivalent to the residential, commercial or light-industrial environment, then the generic standard for this environment, or the relevant product standard, should be applied

3.6

long distance lines

4 Performance criteria

The variety and the diversity of the apparatus within the scope of this standard makes it difficult to define precise criteria for the evaluation of the immunity test results

If, as a result of the application of the tests defined in this standard, the apparatus becomes dangerous or unsafe, the apparatus shall be deemed to have failed the test

A functional description and a definition of performance criteria, during or as a consequence

of the EMC testing, shall be provided by the manufacturer and noted in the test report, based

on one of the following criteria for each test as specified in Tables 1 to 4:

a) Performance criterion A: The apparatus shall continue to operate as intended during

and after the test No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the apparatus is used as intended The performance level may be replaced by a permissible loss of performance If the minimum performance level or the permissible performance loss is not specified by the manufacturer, either of these may be derived from the product description and documentation and what the user may reasonably expect from the apparatus if used as intended

b) Performance criterion B: The apparatus shall continue to operate as intended after the

test No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the apparatus is used as intended The performance level may be replaced by a permissible loss of performance During the test, degradation of performance is however allowed No change of actual operating state or stored data is allowed If the minimum performance level or the permissible performance loss is not specified by the manufacturer, either of these may be derived from the product description and documentation and what the user may reasonably expect from the apparatus if used as intended

c) Performance criterion C: Temporary loss of function is allowed, provided the function is

self-recoverable or can be restored by the operation of the controls

5 Conditions during testing

The equipment under test (EUT) shall be tested in the expected most susceptible operating mode e.g identified by performing limited pre-tests This mode shall be consistent with normal applications The configuration of the test sample shall be varied to achieve maximum susceptibility consistent with typical applications and installation practice

If the apparatus is part of a system, or can be connected to auxiliary apparatus, the apparatus shall be tested while connected to the minimum representative configuration of auxiliary apparatus necessary to exercise the ports in a similar manner to that described in CISPR 22

In cases where a manufacturer's specification requires external protection devices or measures which are clearly specified in the user's manual, the test requirements of this standard shall be applied with the external protection devices or measures in place

The configuration and mode of operation during the tests shall be precisely noted in the test report It is not always possible to test every function of the apparatus; in such cases the most critical mode(s) of operation shall be selected

If the apparatus has a large number of similar ports or ports with many similar connections, a sufficient number shall be selected to simulate actual operating conditions and to ensure that all the different types of termination are covered

The tests shall be carried out at one single set of parameters within the operating ranges of temperature, humidity and atmospheric pressure specified for the product and at the rated supply voltage, unless otherwise indicated in the basic standard

6 Product documentation

If the manufacturer is using his own specification for an acceptable level of EMC performance

or degradation of EMC performance during or after the testing required by this standard, this specification shall be provided in the product documentation available to the user
